Notes from MyBikeThing
The Alias was Specialized’s crossover racing saddle — Body Geometry cutaway channel with a carbon-reinforced shell and hollow Ti rails in this top configuration. Specialized designed the BG line with a sports physician, so it suits a wide range of riders while staying light enough for race duty.
